Product Introduction of 3M Scotch-Weld Core Reinforce Adhesive EC-3903
3M Scotch-Weld Core Reinforce Adhesive EC-3903 is a liquid adhesive specifically designed for bonding and reinforcing crushed honeycomb core structures. This green, organic liquid adhesive is applied via spray, allowing it to easily reach difficult-to-access areas within the honeycomb core. It has a viscosity of 100-300 cps and a flash point of 45°F (7°C).
This adhesive forms a solid coating when cured, effectively reinforcing the core structure. It is best used alongside 3M™ Scotch-Weld™ Structural Adhesive Films AF 126 or AF 126-2 for enhanced performance. Additionally, it can be combined with 3M™ Scotch-Weld™ EC-3703 to reduce viscosity and solids for specific application needs.
